powerpc: Use default strcpy optimization for POWER7

System Internals / glibc - Adhemerval Zanella [linaro.org] - 11 August 2015 08:03 UTC

This patches uses the default strcpy/stpcpy implementation for POWER7/PPC64. This is faster in mostly inputs for benchtests and for multiarch the implementation uses the POWER7 strlen and memcpy.

- string/stpcpy.c (__stpcpy): Use STPCPY to redefine symbol name and cleanup macro usage.
- string/strcpy.c (strcpt): Use STRCPY to redefine symbol name.
- sysdeps/powerpc/powerpc64/multiarch/stpcpy-power7.S: Remove file.
- sysdeps/powerpc/powerpc64/multiarch/stpcpy-ppc64.S: Likewise.
- sysdeps/powerpc/powerpc64/multiarch/strcpy-power7.S: Likewise.
